I would imagine it's just a silk emulsion but might be wrong.
On a flat ceiling/wall I would always recommend that silk emulsion should have a light sanding before applying matt over it. That's not practical on an Artexed ceiling and I've never had a problem with adhesion when applying a good quality matt emulsion over the top of it but if it's a greasy or dirty surface you should clean it with sugar soap and rinse off with clean water, allowing to dry before painting.

should I use pva or something like that as a 1st coat.

No. PVA and paint are not compatible and shouldn't be used together.
If it is a silk emulsion, doing as previously stated should be all that is required. If you use a good trade emulsion you should water it down a little (up to 10% max.) but if you are using standard retail emulsion you can use it neat.
If the existing paint is an oil based eggshell or gloss then you may have to use a high grip primer like Zinsser BullsEye but that will be expensive. A thinned oil based undercoat may also do the trick but you should test either method first before doing the whole ceiling.
